The Leading Source for Global News and Information Covering the Ecosystem of High Productivity Computing
March 14, 2008
This week saw the inaugural meeting of HPC Horizons, a new community of HPC users, vendors, and policymakers dedicated to collaborative discussion of forward-looking topics that push the boundaries of High Productivity Computing. The two-day conference had 125 attendees and featured speakers that represented both traditional and emerging HPC applications. Tabor Communications, the parent company of HPCwire and Tabor Research and the founders of HPC Horizons, billed the event as a prelude to ongoing online discussions among a wider member audience.
The presentations, panel discussions, and community action groups provided a compelling view of future trends in HPC that will be important across both new and established HPC application spaces. Tabor Research observed many common threads and provides the following analysis.
Data Ingest
Massive ingest of data as a limiting factor to HPC scalability was mentioned by several speakers, including a keynote address by Dr. J. Craig Venter, well known throughout the industry for his work in mapping the human genome. The Venter Institute is now investigating microbial life forms, which represent over half the biomass on earth and may hold the key to finding sustainable bio-energy sources or understanding the synthesis of life. Dr. Venter noted that a major challenge currently facing biologists is to gather as much genetic information from the microbial world as possible. A barrel of seawater can yield thousands of new microbial species to analyze and categorize.
Deborah Gracio of Pacific Northwest National Laboratories also discussed data-intensive and data-streaming applications. She noted that advances in high-throughput sensors can easily overwhelm data storage capabilities, giving the example of a proteomics mass spectrometer that was run at about 1 percent of capability because it would take over all of PNNL's storage within two days if run at full capacity. She noted that data filtering and analysis needs to be done close to the sensor, and the multithreaded architectures work well for problems with large irregular memory access.
This level of data influx -- massive amounts of data points for analysis coming from disperse points around the periphery of a system -- is mirrored in other types of emerging applications, such as surveillance, online gaming, logistics, virtual reality networks, or trading analysis. Many of these applications involve real-time or near real-time analysis requirements, and they involve a wide range of data or file types. To address the challenge, many users and vendors suggested the need to move computation closer to the data source.
Predictive Networks
In an opening keynote, Jaron Lanier of UC Berkeley discussed latency as applied to virtual reality systems. In a compelling analogy, he pointed out that the human brain has relatively poor latency in communication between different sections, and he posited that the reason the brain is such a fast computer is due to its predictive capabilities, with each section predicting the information it will receive from other sections ahead of data arrival and then adjust to any variances with the actual information as it comes in.
As the discussions moved toward other latency-sensitive applications, the development of predictive networks was a consistent theme. Several users suggested the need to compute ahead on likely dimensions in order to hide latencies and allow applications to run well at scale.
Distributed computation can also be used to reduce latency issues. For example, two separate views of the flight of a ball can be computed from the initial position and trajectory. Computed independently, these become two halves of a predictive system.

Many organizations that could benefit from the use of HPC clusters find that it is complicated to get the systems up and running because of limited IT resources or the complexities of the clusters themselves. Learn how the Intel Cluster Ready program, for which Dell was an original partner, seeks to address this challenge for entry level and mid-range HPC users.
BlueArc's Titan architecture represents an evolutionary step in file servers by creating a hardware-based file system that can scale bandwidth, IOPS, and overall data capacity well beyond conventional software-based devices. With its ability to virtualize a massive storage pool of up to four usable petabytes of tiered storage, Titan can scale with growing data requirements, offering a competitive advantage for businesses, researchers, or other enterprises seeking to better manage data growth while still ensuring optimal performance.
